As shown in figure, the sensor can sense the vibration caused by finger pressing.

Simulation of piezoelectric vibration sensor based on piezoelectric ceramic production process to transform vibration signal, when the piezoelectric ceramic vibration signal is generated, using a combination of Arduno plate and the special sensor etension, Arduno analog can sense weak vibration signals, can realize the interactive work related with the vibration, such as electronic drum interactive works.

DFRobot version of the sensor module, to bring you more surprises:

Operating voltage to adapt to 3.3V and 5V power supply.

There is a big A small port on the side, indicating that this is a simulation of the sensor.

On the back of a small vibration mark, indicating vibration sensor.

On the board, with high quality joints, can withstand thousands of times plug, ensure firm contact, good.

Heavy gold process, not only to ensure the performance of the module, but also with a golden luster oh!

Note: the port layout of the new analog sensor has the following improvements.
